<br />- 13- <br />Rule 6.1.20 (7) (d): The applicant is required to describe, with maps and narrative, the monitoring <br />systems, etc. employed or to be employed to evaluate the effectiveness of each Environmental <br />Protection Plan facility and activity. The applicant has supplied two maps, i.e. Fiwre B-I and Drawing <br />10.1, both of which indicate the locations of certain ground water monitoring sites. It is the Division's <br />understanding [hat Fiwre B-1 is to illustrate the existing ground water monitoring sites and Drawing <br />10.1 the proposed Amendment 8 ground water monitoring program, including some ground water <br />monitoring wells recently drilled and completed, i.e. PGMW- IA and IB and SGD9W-4A and 4B. If [he <br />applicant intends, as has been reported, to install a wound water monitoring well near the new ADR <br />processing pond, then that well location is missing from Drawing 10.1. Furthermore, Fiwre B-1 does <br />not contain locations for existing monitoring wells GVMW-8A, SGMW-3B and WCMW 2-65, all of <br />which were sampled and reported during 1999. In addition, Table B-l, which is to provide a <br />corresponding summary of the existing ground water monitoring sites, does not include current ground <br />water monitoring wells GVMW-8A or WCMW 2-65. <br />CC&V should sup~v aoorooria[ely revised versions of Drawing ]0.1. Fiwre B-1 and Table B-1. <br />C. Rule 6.4.20 (8) (b): The applicant is required to identify al] known aquifers and related subsurface water <br />bearing fracture systems within 2 miles of the affected lands and provide the general direction and rate <br />of flow of groundwater in these aquifers and fracture systems. The host granite and diatreme are <br />identified and accepted by the Division as the two major water bearing units in the azea; [he direction of <br />preferential flow in these units is described in Appendix 1, Volume II. The applicant, however, has <br />acknowledged significant ground water flow from perched aquifers encountered by present mining, <br />presumably in the diatreme. Flow is also acknowledged in an "upper, and shallow, ground water system <br />within the stream colluvial and alluvial sediments." While any flow direction of the ground water in <br />perched aquifers located in the diatreme might be assumed to be similar to that described for the <br />diatreme overall, the amendment narrative does not adequately describe the directions of flow of <br />groundwater in the colluvial-alluvial system. Elements of the colluvial-alluvial system, if associated <br />with the various streams draining from the diatreme, have the potential not only to be adversely <br />impacted by the mine but to convey the result of those impacts from the mine site within the diatreme to <br />areas outside. <br />CC&V should fully satisfy the requirements of this Rule, i.e. indicate where, within two miles of the <br />lands to be affected by the mining, colluvial-alluvial bodies and anv related subsurface ground water <br />bearing fracture systems are located and the direction of eround water Flow in them. <br />D. Rule 6.4.20 (8) (e): The applicant is required to describe and illustrate the hydrogeology of the area <br />where surface or ground water may be impacted by the Designated Mining Operation. The description <br />and illustration should include those geologic strata and fracture systems that have the potential to <br />transmit ground water. As indicated previously in this review, the application acknowledges [hat <br />around water flow occurs in "an upper, and shallow, ground water system within the stream colluvial <br />and alluvial sediments." The application, however, does not sufficiently describe and illustrate the <br />elements of the colluvial-alluvial ground water bearing system and related fracture systems. <br />CC&V should fulh~ satisfy the requirements of this Rule, i.e. describe and illustrate the <br />occutTences of colluvial-alluvial eround water bearing strata and related fraetL'fe systems on and ~+i:? ir. <br />'? miles of the land to be affected by the operation. <br />E. Rule 6.4?0 (9) (a): Thz applicant is required to indicate the existine and reasonably potential future <br />eround water uses on and within 2 miles down-gradient of the affected lands. The application does state <br />that no use is being made of eround water encountered within the diatreme nor is any use expected in <br />the future bzcause of the drainage of eround water from the diatreme b+ [he varous drainage tunnels. <br />
